  Professor H. C. Longuet-Higgins

  The Chemical Laboratory

  University of Cambridge

  Cambridge, England

  Dear Longuet-Higgins:

  I have read with interest your paper by Roberts, in the last issue of the Proceedings of the Royal Society, on the electronic structure of an icosahedron of boron atoms. I am in general pleased with your results, but there is one point that I should like to discuss with you. Some years ago I began work along similar lines, and the work is in fact being continued now by Dr. Hoerni, who will remain here for another year.

  You have reached the conclusion that the tetragonal structure for boron reported by Hoard and his co-workers cannot be of the closed-shell type. I think that there is a flaw in your argument. First, I am not sure that each of the two tetrahedral boron atoms in the unit must bear an extra electron, and form four single bonds with its neighbors. Let us, however, assume that this is so, and that 16 electrons of the total of 150 in the unit are tied up in this way. There remain 134 electrons. Let us assume that 26 electrons per icosahedron are then involved in filling the closed shells. There then remain 30 electrons per unit, which are to be assigned to the bonds connecting boron icosahedra. There are 20 bonds of this sort per unit, which would require 40 electrons if the bonds were single bonds. I suggest, however, that the bonds are not single bonds, but are three-quarters bonds, requiring only one and one half electrons per bond - that is, I suggest that a treatment of the entire crystal, with the icosahedra conjugated together, would show that this number of electrons corresponds to a closed shell.

  I might point out that your assumption that the outward-pointing orbitals of the icosahedron are all involved in forming single bonds, rather than fractional bonds, does not correspond to the assumption made for the inward-pointing orbitals - namely, that only those with a positive value of the energy parameter (corresponding to stabilization) are to be occupied. In your Table 5 four of the outward-pointing orbitals, rather than 12, are given positive values of the energy parameter. By including the five orbitals with symmetry V, which have a small negative value of this parameter, a total of 9 would be obtained, corresponding to an average of three-quarters occupancy. This is not exactly right, of course, because it includes the two boron atoms bonded to tetrahedral borons, as well as the other ten. But, of course, the icosahedron of boron atoms does not have true icosahedral symmetry in this tetragonal structure, in which two of the twelve boron atoms are bonded to tetrahedral boron atoms, and the other ten are not. I do not think that the argument that you have given is justification for throwing doubt on the structure described by Hoard and his co-workers.

  There is another point that I may make. If your assumption were correct, the boron-boron distance between icosahedra should be significantly less than that within an icosahedron. I do not think that the x-ray evidence supports this. It is true that the structure determinations for B₄C and tetragonal boron are not precise ones. However, the problem is the same in CaB₆, which is the substance which we have also been treating theoretically. In CaB₆ each boron atom forms four bonds within an octahedron, and a fifth bond pointing out from the octahedron. You would probably treat this problem in an analogous way to that in which you have treated the problem of ocosahedral structures, whereas we have been considering the problem of the entire crystal, involving conjugated octahedra. Your assumption would in this case mean that the bonds pointing out from an octahedron are single bonds, involving two electrons per bond, and leaving only 1.2 electrons per bond within the octahedron. Twenty years ago Weinbaum and I made a very careful study of CaB₆, and we were able to show that the boron-boron distances between octahedra are identical, to within 0.01 Å, with those within an octahedron. It is evident that these bonds are of essentially the same type, involving about 1.33 electrons per bond.

  Sincerely yours,

  To: Professor Pauling From: H. Segall Date: 7-11-55 E

  SUBJECT: The Average of Amino Acid Residues Contained in the Unit Cell of Collagen.

  A survey of the recent literature was made to collect consistent on the unit cell dimensions, density and average residue weight for collagen. The most complete work on dry and wet untreated kangaroo tail tendon was reported by Rougvie and Bear (J. Amer. Leather Chemists Assn., 48, 735 (1953)). A less comprehensive investigation was made by Dr. R. A. Pasternak of this Institute and was contained in a report to Professor Pauling on March 11, 1954.

  According to the report of Dr. Schroeder of Nov. 6, 1952 the existing chemical analyses of the amino acid content of mammalian collagen are sufficiently consistent not to warrant any further determinations at present. An average residue weight of 92.6 was taken from the work of Bowes and Kenton (Biochem. J., 43, 358 (1948))

  (1) Rougvie and Bear reported the equatorial spacing of exhaustively dried kangaroo tail tendon as 10.6 A. The sample was dried for one week over P₂O₅ at room temperature. Although this value is slightly higher than other reported values it is consistent with their measurements of the equatorial spacing as a function of the water content of collagen from dry to water saturated specimens. The usual meridional distance of 2.86 Å was also reported. The volume of the hexagonal unit cell is accordingly V = 2.86 x 10.6²/cos 30 = 371.1 A³.

  The density of dry unpurified collagen was determined by flotation in bromheptane and carbon tetrachloride by Rougvie and Bear. Their reported value of 1.34 is close to other reported values of dry collagen and gelatin. The weight for a mole of units is then

  M = V x d x N = 371.1 x 10-24 x 1.34 x 6.023 x 1023 = 299.5 gms

  By taking 92.6 as the average residue weight the average number of amino acid residues in the unit cell, n, is found to be

  [Data Equation]

  The uncertainties in this value of n are the average residue weight (1 or 2%) and the density. The presence of non-collagenous material in the unpurified sample may affect the observed density.

  (2) The experimental values as determined by Dr. Pasternak for hydrated collagen containing 16.3% water are as follows:

  meridional spacing = 2.88 Å

  equatorial spacing = 11.54 Å

  density = 1.32

  By taking an average residue weight of 93.3 and adding 18.6 for the water associated with it he obtained an apparent molecular weight of 111.9. The calculated value of n was 3.15.

  Rougvie and Bear have shown that from 0 to about 20 g water/100 g collagen the sorbed water was effective in increasing the volume of the unit cell according to its normal density of 1.00. Greater hydration increases the volume at a considerable smaller rate. Thus it can be said that Dr. Pasternak’s value of n is fortuitously close to Bear’s value since his water of hydration falls within the 0 to 20 range.

  (3) The value of 3.23 as the average number of amino acid residues in the unit cell of collagen calculated from the data of Rougvie and Bear is probably accurate to 3 or 4 per cent. The reasonably exhaustive work of Rougvie is sufficient for the present.

  SUBJECT Nomination of Harvey Itano

  I have prepared a nomination of Harvey Itano for the Theobald Smith Award ($1000 and a bronz [sic] medal) which will be presented to someone during the Association's 122nd meeting, to be held in Atlanta, Georgia, this December. Would you he willing to prepare a letter supporting the nomination, in which you stress the nominee's personality, training, and research work? I think that in particular a statement such as you have made to me orally about the high opinion in which Dr. Itano is held personally by members of your Division of Biology would be especially needed. I should like to have seven signed copies of your letter. I enclose a draft of the nomination that I have prepared.

• Memorandum: Herbert Segall to Linus Pauling. [Filed under LP Science: Box #6.004, Folder 4.18]

  The average number of amino acid residues in the unit cell of collagen was recalculated from the independent work of Bear and Pasternak. An estimate of the reliability of this average number was made.

  1) The average number of amino acid residues was calculated by the following formulae:

  [Data Equation]

  n = average number of residues in a unit cell

  f = fraction of total weight due to collagen

  N = Avogadro’s number

  V = volume of unit cell (hexagonal)

  d = density

  R = average residue weight

  c = meridional spacing

  b = equatorial spacing

  2) In order to evaluate the fraction f from a nitrogen determination it is necessary to know the per cent of nitrogen in a sample of pure collagen. The per cent of nitrogen was calculated from the amino acid composition of mammalian collagen as given by Bowes and Kenton (Biochem. J., 43, 358 (1948)). In 10⁵ gms. of collagen thre are 1278 gm-atoms of nitrogen or 17,902 gms. The combined amide nitrogen of aspartic acid and glutamic acid was taken as 0.66 per cent from the experimental determination by Bowes and Kenton, although the calculated values from the amino acid composition are 0.66 and 1.08 per cent respectively.

  calculated per cent of nitrogen

  17.90 (amino acid nitrogen)

  0.66 (amide nitrogen)

  18.65 total

  Bowes and Kenton determined the total nitrogen experimentally and found 18.6 per cent nitrogen. The fourth figure in the calculated value is not really significant since the data of Bowes and Kenton account for only 99.6 gms. of residue for each 100 gms. of collagen. The calculated per cent of nitrogen was taken as 18.6.

  3) The following data were obtained from the work of Rougvie and Bear (J. Amer. Leather Chemists Assn., 48, 735 (1953)) on thoroughly dried untreated kangaroo tail tendon.

  d = 1.34

  c = 2.86 Å

  b = 10.6 Å

  % N = 18.0

  f = 18.0/18.6 = 0.969

  R = 92.6 (Bowes and Kenton)

  V = 2.86 x 10.6²/cos 30 = 371.1 ų

  n = 0.968 x 6.023 x 10²³ x 371.1 x 10^-24 x 1.34/92.6

  n = 3.13

  In a previous report on July 11, 1955 the fraction f had not been taken into account so that the value of n was erroneously reported as 3.23.

  4) The following data were obtained from Dr. R. A. Pasternak of this Institute who worked on partially hydrated untreated kangaroo tail tendon.

  d = 1.32

  c = 2.88 Å

  b = 11.54 Å

  % N = 15.72 (wet basis)

  f = 15.72/18.6 = 0.845

  V = 2.8 x 11.54²/cos 30 = 442.9 ų

  n = 0.845 x 6.023 x 10²³ x 422.9 x 10^-24 x 1.32/92.6

  n = 3.21

  5) A second value of n can be calculated from Dr. Pasternak’s data by using the water and wash determination. The water content (15.9%) and cation content (0.4%) were assumed by to be the only impurities.

  f = 1 – (15.9 + 0.4) = 0.837

  Using the same data as given in section 4) except for the value of f we obtain

  n = 3.18

  In the previous report the value of n was calculated by using an average residue weight of 93.3 which Dr. Pasternak calculated from the amino acid composition as compiled by Tristram (Advances in Protein Chemistry, Vol. V, 143 (1949)). The average residue weight of 92.6 (Bowes and Kenton) was taken in order to be consistent with the calculated nitrogen content of collagen.

  6) Consideration of errors in n – The presence of impurities in untreated collagen can cause a number of serious but indeterminable errors. a) In the nitrogen determination any nitrogenous impurity will give a high value to the fraction f and cause a positive error. b) In the water and ash determination any impurity that is not water or ash will give a high value to f and cause a positive error. c) The fraction of the weight in the unit cell due to collagen may be greater than the experimental f since some of the impurity may be outside the unit cell and thus cause a negative error. d) The experimental density is the average density of collagen plus the impurities not in the collagen. This error can be plus or minus but it is more likely to be negative in a hydrated sample. e) There may be local variations of density and average residue weight along the helix of collagen but the local values of d/R can be expected to be close to the average value d/Ro. f) It is possible to give some numerical estimates of the errors involved in the deviations of the following quantities are based on two measurements of each quantity.

  [Data Talbe]

  The two best values of the average residue weight (92.6 and 93.3) have an average deviation of 0.38% but they are based on essentially the same data. No estimate is available for the meridional spacing. The errors due to true density and average residue weight are probably underestimated. Based on these estimates the minimum uncertainty in the value of n is about ± 1.5% or ± 0.05 residues per unit cell. The three values of n give the following average value:

  3.13 (Bear)

  3.21 (Pasternak)

  3.18 ( “

  Average = 3.17 ± 0.03

  The average deviation falls within the estimated minimum uncertainty of ± 0.05. The present data indicate that n is slightly but significantly larger than 3.

• Letter from LP to Bob Potter RE: Since gamma rays are not deflected by magnetic or electric fields, the same principle used in the electron microscope cannot be used in a gamma ray microscope. The index of refraction of material substances for gamma rays is essentially unity for all substances, so lenses cannot be used to focus gamma rays. The only way a gamma ray microscope might be made would be to have a small source of gamma rays, close to the object to be magnified, and a photographic plate far away. If an object absorbed gamma rays strongly enough, it would cast a shadow, which would be enlarged in the ratio of the distance from the source to the plate divided by the distance from the source to the object being photographed. The disadvantage is that gamma rays penetrate matter so strongly that ordinary objects would not cast a significant shadow.

Replied to the editor's request for suggestions; these comments will reach LP soon. Reviewed the notes of the student who announced the equivalence to free rotation of molecules with even-odd rotational symmetries on the two ends. Finds that the student's results were based upon an unwarranted approximation. Thus, a gradual approach to the free rotation does indeed occur with increasing multiplicity of the rotational symmetry.

  Dear Hugo:

  Your letter of 20 April, with the manuscript of your communication to Nature, reached Pasadena while I was on an eastern trip, lecturing at Harvard University, and I have put off answering it after my return, until now.

  I was pleased to see this paper, and to know that you have found the model that I left you to be useful in your work. I agree with you that it is likely that the α helix is present in cytochrome c.

  We have not published an account of our new models anywhere. I have been hoping to include a brief discussion of them in a paper that we have slowly been preparing, dealing with possible configurations of polypeptide chains in collagen.

  With best regards, I am

  Sincerely yours,

  Linus Pauling:W
